Developed by Kojima Productions and Platinum Games, Metal Gear Rising: Revengeance for PC is described as the "full game." It will run at 60 frames-per-second on PC, though no other PC-specific features were announced.
Metal Gear Rising: Revengeance launched for Xbox 360 and PlayStation 3 in February. Platinum Games previously stated that it is interested in making games for the PC and publishing them through Valve's Steam downloadable games service.
